The specific embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
Referring to Fig. 1-3, present embodiment mainly is comprised of four parts: the double-row bearing part, the constant-velocity universal joint part, film temperature, acceleration pick-up part and ABS wheel speed sensors part, parts comprise mandrel 1, outer ring 2, back-pressure lid 3, seal ring 4, end cap 5, rolling body 6, little inner ring 7, buckle 8, O type circle 9, O RunddichtringO 10, retainer 11, diaphragm type Temperature/Vibration acceleration pick-up 12, back-up ring 13, end cap 14, seal ring 15, seal ring 16, end cover 17, retainer 18, universal-joint rolling body 19, semiaxis 20, inner race 21, boss bolt 22, rolling body 23, gear ring of wheel speed sensor 24, wheel speed sensors 25 etc., annexation and the principle of work of each parts see for details hereinafter.
Mandrel 1 has an endoporus, the first paragraph diameter of mandrel 1 outer wall large (shown in Figure 1 right section), this section has bolt hole, the axis of this bolt hole parallels with the axis of mandrel 1, boss bolt 22 is pressed into by interference fit in the bolt hole of mandrel 1, mandrel 1 is fixed on the wheel hub of automobile.When intelligent hub-bearing unit was installed on the automobile, mandrel 1 was connected with wheel hub by boss bolt 22, rotates with the rotation of wheel hub.
Another section of mandrel 1 is that the second segment diameter is less, normal-running fit outer ring 2 outside the second segment.Be processed with the twice ring raceway on the endoporus of outer ring 2.Corresponding, the second segment of mandrel 1 also is processed with raceway near an end outer wall of larger section of diameter, and this raceway is corresponding with outer ring 2 an inwalls raceway wherein.A plurality of conical rolling elements 23 are packed into behind the retainer 27, insert mandrel 1 and outer ring 2 aforementioned corresponding raceways (retainer 27 does not touch or movable the cooperation mutually with mandrel 1, outer ring 2) again, thereby so that rolling body 23 can between two raceways, move.The other end outer wall of mandrel 1 second segment and little inner ring 7 transition fit, both heavy keying fit, and pass through technique for riveting so that this end outward flanging of mandrel is realized the location to little inner ring 7, thereby retrained the movement vertically of little inner ring 7.The outer wall of little inner ring 7 is along circumferentially also being processed with raceway, and this raceway is corresponding with another raceway of outer ring 2 inwalls.A plurality of conical rolling elements 6 are packed into behind the retainer 11, insert the corresponding raceway (retainer 11 does not touch or movable the cooperation mutually with little inner ring 7, outer ring 2) in little inner ring 7 and outer ring 2, so that rolling body 6 can move between two raceways again.Each rolling body is loaded in the hole of corresponding retainer, and the part protrudes from retainer, so that rolling body is in motion process, retainer and outer ring, mandrel/little inner ring keep certain relative position.By above-mentioned mounting structure, so that normal-running fit between mandrel and outer ring.
The first port of outer ring 2 is equipped with back-up ring 13 and seal ring 15, and fixing by end cap 14, seals, and anti-sealing and silt enter hub inside and damages rolling body 23 and corresponding raceway.
Transition fit back-pressure lid 3 in the second port of outer ring 2, and the seal ring 4 of packing into, the rectangular shape of cross-sectional plane of back-pressure lid 3, the second port inner wall of its annular edge outer wall and outer ring 2 is affixed, and its annular edge is insert-seal circle 4 radially.Little inner ring 7 outer walls at this position are inserted in end cap 5, the rectangular shape of the cross-sectional plane of end cap 5, its circumferential lateral edge seal the radial gap of little inner ring 7 and outer ring 2, and its annular edge is affixed on the outer wall of little inner ring 7, and be pressed on outward within the part of seal ring 4, by O RunddichtringO 10 seal ring 4 is pressed in end cap 5.O RunddichtringO 10 is pressed on seal ring 4 on the end cap 5.Seal ring 4 seals, and anti-sealing enters hub internal damage rolling body 6 and corresponding raceway.End cap 5 prevents that the foreign material such as silt from entering inside and damaging parts such as rolling body 6 and raceway etc.
Captive joint with inner race 21 by screw thread in the end of semiaxis 20, the inner of inner race 21 snaps in buckle 8, and buckle 8 is stuck on the semiaxis 20, axially is moved along semiaxis to prevent inner race 21.The endoporus of mandrel 1 is stretched in the end of semiaxis 20, and inner race 21 is within the endoporus of mandrel 1.Inner race 21 forms many straight trough roads, and the straight trough road is parallel to the axis of semiaxis 20.Corresponding, also being processed with some straight trough roads on the inner hole wall of mandrel 1, the straight trough road is parallel to the line of centers of mandrel endoporus.Universal-joint rolling body 19 is installed in the hole of retainer 18, and the part protrudes from retainer 18.Pack between the endoporus and inner race 21 of mandrel 1 with the retainer 18 of universal-joint rolling body 19, and universal-joint rolling body 19 is inserted the inner race 21 straight trough road corresponding with mandrel 1 endoporus; And retainer 18 is between the endoporus and inner race 21 of mandrel 1, retainer 18 constraint universal-joint rolling bodys 19 position certain with the endoporus of mandrel 1 and inner race 21 maintenances when motion.Universal-joint rolling body 19 can rotate in the straight trough road and move and move axially along the straight trough road.Semiaxis 20 can swing certain angle by relative mandrel 1 in a circumferential direction with inner race 21.Mandrel 2 endoporus snap in O type circle 9 near the second end port, and semiaxis 20 passes O type circle 9, movable cooperation between the two, and O type circle 9 limits the distance that moves axially of retainer 18, inner race 21 and semiaxis 20.
The load that the automobile transmission comes is by two row rolling bodys 6,23 shareds.Automobile power is delivered on inner race 21, universal-joint rolling body 19, mandrel 1 and the boss bolt 22 successively from semiaxis 20, thereby drives running car.
Two cover diaphragm type Temperature/Vibration acceleration pick-ups 12 are installed in respectively in the outer wall groove of outer ring 2, and both are 120 to spend with the line angle of mandrel 1 interior central point of hole.During running car, the temperature of two cover diaphragm type Temperature/Vibration acceleration pick-up output hub bearing units and the vibration acceleration numerical value of three directions, the running state that is used for the monitoring hub-bearing unit, in case temperature and vibration acceleration numerical value occur unusual, ECU (Electrical Control Unit) will provide warning, and reminding driver overhauls hub-bearing unit.
As shown in Figure 1, gear ring of wheel speed sensor 24 is fixed on the second segment outer wall of mandrel 1 by interference fit.As shown in Figure 3, wheel speed sensors 25 is installed in the endoporus 26 of outer ring 2, for detection of the output pulse count of gear ring of wheel speed sensor 24.Gear ring of wheel speed sensor 24 rotations, output pulse signal are to wheel speed sensors 25, and the tach signal of wheel speed sensors 25 output wheels is to the ABS ECU (Electrical Control Unit).
Above embodiment is only unrestricted for explanation the utility model; those of ordinary skill in the art will be appreciated that; can make amendment or on an equal basis replacement to the technical solution of the utility model; the spirit and scope that do not break away from technical solutions of the utility model, it all falls into protection domain of the present utility model.
